摘要: The crystal and magnetic structure of Pr0.1Sr0.9MnO3 manganite has been studied by the neutron diffraction at high pressures up to 5 GPa in temperature range 10–295 K. At normal pressure decreasing appearance C-type (TN = 220 K) G-type 180 antiferromagnetic states occurs, which is accompanied a structural phase transition from cubic (Pm\( \bar 3 \)m space group) tetragonal (I4/mcm group). It shown that increases with coefficient dTN/dP 4.0(5) K/GPa weakly depends on pressure.
